Foreign-Born Individuals with HIV in King County, WA: A Glimpse of the Future of HIV?

The Promise of Pre-Exposure Prophylaxis - Examining Awareness, Knowledge, and Willingness to use Different Modalities Among US-Based African Immigrants

This study aims to describe and understand the relationship between sociodemographic factors and PrEP awareness, and willingness to use a PrEP modality (oral or injectable).Despite the availability of effective prevention tools such as HIV preexposure prophylaxis (PrEP), African immigrants in the United States are disproportionately affected by HIV. Although PrEP can significantly reduce HIV infection in this population, research evidence on PrEP outcomes, such as awareness, knowledge, and willingness to use, is extremely limited. Between April and May 2022, 92 participants completed an online survey assessing their awareness, knowledge, and willingness to use oral or injectable PrEP. The association between sociodemographic characteristics and PrEP-related measures was examined using descriptive and Pearson's chi-squared or Fisher's exact tests. Participants (N = 92) were born between 1990 and 1999 (46.7%), female (70.76%) and highly educated (59.6%). About 52.2% were unaware of PrEP, and 65.6% were willing to use a PrEP modality. Findings indicate that individuals who reported being aware of PrEP demonstrated a high level of knowledge regarding the medication. Having a healthcare provider was associated with PrEP awareness and willingness to use, while educational status was associated with PrEP awareness. 51.1% of participants were willing to use an oral pill for prevention and 47.8% were willing to use injectable PrEP. Our findings highlight the need for PrEP-related research and interventions for African immigrants to increase awareness and provide options for HIV prevention, as African immigrants are currently not well-represented in PrEP delivery systems in the US.

Impact of HIV/AIDS on African-born Women Living in the United States: a Systematic Review

BACKGROUND

There is paucity of surveillance data about African-born women (ABW) living with HIV/AIDS in the USA. Out of the 50 US states, only Washington state and Minnesota report HIV surveillance data about African-born people, and Minnesota is the only state that reports data about ABW, specifically. In Minnesota, ABW have the largest prevalence rate of HIV/AIDS among all women. In Washington state, foreign-born Black people have the highest incidence of HIV behind white people and foreign-born Hispanic people. This study aims to better understand the impact HIV/AIDS on ABW.

METHODS

This systematic review is based on articles available on three databases (PubMed, Embase, and Cochrane Library). Databases were searched for articles that included quantitative and/or qualitative findings about the impact of HIV/AIDS on ABW in the USA.

RESULTS

Several themes were identified including disproportionate impact of HIV/AIDS on ABW, barriers to care, low sexual health knowledge, HIV-related stigma, and limited HIV testing. Based on 2013 data, the incidence of HIV among ABW was 12 times higher than the incidence among women in the general US population. In 2008-2014, ABW had the smallest decline in HIV diagnosis rate when compared to US-born men and women, African-born men, and Caribbean-born men and women. Barriers that ABW face when trying to access care include, language barriers, fear of deportation and difficulty navigating the US healthcare system.

CONCLUSION

ABW living in the USA are uniquely impacted by HIV/AIDS. Lasting negative health consequences can be mitigated by improving HIV surveillance and investing in further studies about this population.

Post-migration HIV acquisition among african immigrants in the U.S

BACKGROUND

African immigrants in the U.S. are more likely to have a late HIV diagnosis than U.S.-born people, potentially leading to onward transmission. We sought to determine the proportion of African-born people living with HIV (APLWH) who (1) had tested HIV negative prior to diagnosis, and (2) likely acquired HIV in the U.S.

METHODS

We interviewed APLWH from 2014 to 2017 and estimated the proportion with post-migration HIV acquisition based on clinical data, HIV testing history, immigration date, and behavioral data.

RESULTS

Of 179 participants, 113 (63%) were women. Less than half (44%) reported a negative HIV test prior to diagnosis. Among 142 (79%) participants with sufficient data to evaluate post-migration HIV acquisition, we estimate that 29% acquired HIV post-migration. Most APLWH acquire HIV prior to immigration.

DISCUSSION

Approximately one-quarter of APLWH acquire HIV post-migration and HIV testing is infrequent, highlighting the need for prevention efforts for African immigrants in the U.S.

Harambee! 2.0: The Impact of HIV-Related and Intersectional Stigmas on HIV Testing Behaviors Among African Immigrant Communities in Seattle, Washington

African immigrants are disproportionately affected by HIV compared to U.S.-born individuals, and early HIV testing is the key challenge in ending the HIV epidemic in these communities. HIV-related stigma appears to be the most significant barrier to testing for HIV among African communities in King County, WA. In this formative study, we conducted thirty key informant interviews and five focus group discussions (n = total 72 participants) with Ethiopian, Somali, and Eritrean people living with HIV, health professionals, religious and other community leaders, and lay community members in King County to better understand HIV-related and intersectional stigmas' impact on HIV testing behaviors. We used inductive coding and thematic analysis. Participants from all communities reported similar themes for HIV-related and intersectional stigmas' influences on HIV testing behaviors. Misconceptions or poor messaging, e.g., regarding treatability of HIV, as well as normative or religious/moral beliefs around pre/extramarital sex contributed to HIV-related stigma. Intersecting identities such as immigrant status, race/ethnicity, and having a non-English language preference, all intermingle to further influence access to the U.S. healthcare system, including for HIV testing. These findings can be used to inform future research on community-led approaches to addressing early HIV testing amongst African immigrant communities.

"They Wait until the Disease Has Taking over You and the Doctors Cannot Do Anything about It": Qualitative Insights from Harambee! 2.0

African immigrants make up a large subgroup of Black/African-Americans in the US. However, because African immigrant groups are typically categorized as "Black," little is known about their preventative healthcare needs. Differences in culture, life and healthcare experiences between African immigrant populations and US-born people may influence preventive health care uptake. Thus, policymakers and healthcare providers lack information needed to make informed decisions around preventive care for African immigrants. This formative study was conducted among the largest East African immigrant communities in King County, WA. We recruited religious leaders, community leaders, health professionals, and lay community members to participate in thirty key informant interviews and five focus group discussions (n = 72 total), to better understand preventative healthcare attitudes in these communities. Through inductive coding and thematic analysis, we identified factors that impact preventative healthcare attitudes of the Somali, Ethiopian and Eritrean immigrant communities and deter them from accessing and utilizing healthcare. Cultural beliefs and attitudes around preventative healthcare, mistrust of westernized healthcare, religious beliefs/views, intersecting identities and shared immigrant experiences all influence how participants view preventative healthcare. Our results suggest that interventions that address these factors are needed to most effectively increase uptake of preventative healthcare in African immigrant communities.

Combining traditional and molecular epidemiology methods to quantify local HIV transmission among foreign-born residents

OBJECTIVES

We evaluated the ability for molecular epidemiology to augment traditional HIV surveillance beyond the detection of clusters for outbreak investigation. To do this, we address a question of interest to Public Health - Seattle and King County: what proportion of HIV diagnoses among people born outside of the United States are acquired locally?

DESIGN

King County residents diagnosed with HIV, 2010-2018.

METHODS

We linked HIV-1 pol gene sequences to demographic information obtained from the National HIV Surveillance System, Public Health - Seattle and King County case investigation and partner services interviews. We determined the likely location of HIV acquisition based on HIV testing, travel histories and cluster-based molecular analyses.

RESULTS

Among 2409 people diagnosed with HIV, 798 (33%) were born outside of the United States. We inferred the location of acquisition for 77% of people born outside of the United States: 26% likely acquired HIV locally in King County (of whom 69% were MSM, 16% heterosexual), and 51% likely acquired HIV outside of King County (primarily outside of the United States). Of this 77% of people for whom we inferred the location of HIV acquisition, 45% were determined using traditional epidemiology methods and an additional 32% were inferred using molecular epidemiology methods.

CONCLUSION

We found that the National HIV Surveillance System misclassified the majority of HIV-infected foreign-born residents as 'new' local infections, and that these cases contribute to an overestimate of local incidence. Our findings highlight how molecular epidemiology can augment traditional HIV surveillance activities and provide useful information to local health jurisdictions beyond molecular cluster detection.

The associations of population mobility in HIV disease severity and mortality rate in China

Background

Human immunodeficiency virus (HIV) infection has become a chronic disease and attracted public attention globally. Population migration was considered hindering the control and management of HIV infection, but limited studies have explored how population mobility could influence the development of HIV-related complications and overall prognosis.

Methods

We enrolled hospitalized HIV patients in this cross-sectional study between January 1, 2006, and December 31, 2016. We extracted demographic, hospitalization, and patient diagnosis data. Patients were divided into three groups according to the population type: (I) resident of Guangzhou City (local resident); (II) migrant outside of Guangzhou City but within Guangdong Province (migrant within the province); and (III) migrant outside of Guangdong Province (migrant outside the province). To represent the prognosis of HIV, in-hospital death was defined as the worst outcome, whereas vision-related events were considered moderate-to-severe complications. Logistic regression models were used to analyze factors influencing the prognosis of HIV.

Results

Eight thousand and six hundred thirty-one inpatients (14,954 cases) were enrolled. The overall mortality was 7.9%, decreasing from 21.5% in 2006 to 3.8% in 2016. The prevalence of vision-related events was 14.4% between 2015 and 2016. Compared to local patients, migrant patients (within and outside the province) were younger, had significantly less access to health insurance, fewer hospitalization admissions, longer hospital stays, and a higher proportion of physical work (P<0.01). Furthermore, they had a higher prevalence of vision-related events (16.2% and 17.4% in migrant patients within the province and outside the province, respectively vs. 9.5%) and infectious diseases, but lower in-hospital mortality (5.9% and 7.0% vs. 12.3%) than local patients. Migrants correlated negatively with in-hospital death [odds ratio (OR) 95% CI, 0.37 (0.29–0.48) and 0.52 (0.40–0.68)] but correlated positively with vision-related events [OR (95% CI), 2.08 (1.54–2.80) and 2.03 (1.47–2.80)].

Conclusions

Migrant patients have significantly poorer access to health insurance, with an increased risk of developing moderate-to-severe HIV infection but a decreased risk of in-hospital death, indicating a trend toward withdrawing treatment in migrant patients when they have advanced diseases. Managements such as optimizing access to health insurance and improving follow-up visits for HIV infection should be considered in the context of the population mobility of HIV patients.

Travelling with HIV in the XXI century: Case report and narrative review

The number of migrants and travellers has grown in recent decades. This phenomenon is also true of people living with HIV, given their much-improved life expectancy and quality of life. A significant number of travellers with HIV are migrants returning to their home countries to visit friends and relatives (VFRs). This population constitutes a high-risk group because they travel for longer and often to rural and remote areas and have closer contact with the local population. In this review we discuss the sociodemographic characteristics of travellers with HIV, the differences between conventional travellers and VFRs, and the risks of HIV acquisition and transmission during travel. We also present the most relevant travel-associated illnesses and highlight the particularities of pre-travel advice given to this population, including immunosuppression, responses to vaccines, high incidence of comorbidities, drug interactions, legal and language barriers. The need to integrate these factors based on far less evidence than that available for the general population makes pre-travel advice for travellers with HIV genuinely challenging.

The Epidemiology of HIV Among People Born Outside the United States, 2010-2017

OBJECTIVE

Although some studies have reported a higher incidence of HIV infection among non-US-born people than among US-born people, national data on this topic are scarce. We compared the epidemiology of HIV infection between US-born and non-US-born residents of the United States and examined the characteristics of non-US-born people with diagnosed HIV infection by region of birth (ROB).

METHODS

We used a cross-sectional study design to produce national, population-based data describing HIV infection among US-born and non-US-born people. We analyzed National HIV Surveillance System data for people with HIV infection diagnosed during 2010-2017 and reported to the Centers for Disease Control and Prevention (CDC). We compared data on demographic characteristics, transmission risk category, and stage 3 infection (AIDS) classification within 3 months of HIV diagnosis, by nativity and ROB.

RESULTS

During 2010-2017, 328 317 children and adult US residents were diagnosed with HIV infection and were reported to CDC: 214 973 (65.5%) were US-born, 50 301 (15.3%) were non-US-born, and 63 043 (19.2%) were missing data on country of birth. After adjusting for missing country of birth, 266 147 (81.1%) people were US-born and 62 170 (18.9%) were non-US-born. This group accounted for 15 928 of 65 645 (24.2%) HIV diagnoses among girls and women and 46 242 of 262 672 (17.6%) HIV diagnoses among boys and men. A larger percentage of non-US-born people than US-born people had stage 3 infection (AIDS) at HIV diagnosis (31.2% vs 23.9%). Among non-US-born people with HIV diagnoses, 19 876 (39.5%) resided in the South.

CONCLUSIONS

Characterizing non-US-born people with HIV infection is essential for developing effective HIV interventions, particularly in areas with large immigrant populations.

Women from afar: an observational study of demographic characteristics and mortality among foreign-born women living with HIV in the Women's Interagency HIV Study (WIHS) in the United States 1994-2016

INTRODUCTION

Foreign-born persons comprise ~13% of the US population. Immigrants, especially women, often face a complex set of social and structural factors that negatively impact health outcomes including greater risk of HIV infection. We described socio-demographic, clinical and immunological characteristics and AIDs and non-AIDS death among foreign-born women living with HIV (FBWLWH) participating in the US Women's Interagency HIV Study (WIHS) in the US from 1994 to 2016. We hypothesized that FBW will experience higher AIDS-related mortality compared to US-born women (USBW).

METHODS

The WIHS is a multicenter prospective observational cohort study of mostly women living with HIV (WLWH). The primary exposure in this analysis, which focused on 3626 WLWH, was self-reported country of birth collapsed into foreign-born and US born. We assessed the association of birthplace with categorized demographic, clinical and immunological characteristics, and AIDS/non-AIDS mortality of WLWH, using chi-squared tests. Proportional hazard models examined the association of birthplace with time from enrolment to AIDS and non-AIDS death.

RESULTS

Of the 628 FBW, 13% were born in Africa, 29% in the Caribbean and 49% in Latin America. We observed significant differences by HIV status in socio-demographic, clinical and immunological characteristics and mortality. For both AIDS and non-AIDS caused deaths FBW WLWH had lower rates of death. Adjusting for year of study enrolment and other demographic/clinical characteristics mitigated FBW's statistical survival advantage in AIDS deaths Relative Hazard (RH = 0.91 p = 0.53), but did not substantively change the survival advantage in non-AIDS deaths RH = 0.33, p < 0.0001).

CONCLUSION

Foreign-born WLWH exhibited demographic, clinical and immunological characteristics that are significantly different compared with women born in the US or US territory. After adjusting for these characteristics, the FB WLWH had a significantly lower hazard of non-AIDS but not AIDS mortality compared to women born in the US or a US territory. These findings of non-increased mortality can help inform models of care to optimize treatment outcomes among FBWLWH in the United States.

Challenges in Recruiting African-Born, US-Based Participants for HIV and Tuberculosis Research

Research is critical for developing HIV and tuberculosis (TB) programming for U.S. African-born communities, and depends on successful recruitment of African-born people. From January 2014 to June 2016, we recruited African-born people for HIV and TB research in King County, Washington. We compared the characteristics of study participants and the underlying populations of interest, and assessed recruitment strategies. Target enrollment for the HIV study was 167 participants; 51 participants (31%) were enrolled. Target enrollment for the TB study was 218 participants; 38 (17%) were successfully recruited. Of 249 prior TB patients we attempted to contact by phone, we reached 72 (33%). Multiple recruitment strategies were employed with variable impact. Study participants differed from the underlying populations in terms of gender, country of origin and language. Inequities in research participation and in meaningful opportunities for such participation may exacerbate existing health disparities.

Harambee!: A pilot mixed methods study of integrated residential HIV testing among African-born individuals in the Seattle area

Background

African-born individuals in the U.S. are disproportionately affected by HIV yet have low HIV testing rates. We conducted a mixed methods study to assess the uptake and feasibility of a novel strategy for integrating HIV testing into residential health fairs among African-born individuals in Seattle, WA.

Methods

From April to May 2018, we held six health fairs at three apartment complexes with high numbers of African-born residents. Fairs included free point-of-care screening for glucose, cholesterol, body mass index, blood pressure, and HIV, as well as social services and health education. The health fairs were hosted in apartment complex common areas with HIV testing conducted in private rooms. Health fair participants completed a series of questionnaires to evaluate demographics, access to health services, and HIV testing history. We conducted 18 key informant interviews (KIIs) with health fair participants and community leaders to identify barriers to HIV testing among African-born individuals.

Results

Of the 111 adults who accessed at least one service at a health fair, 92 completed questionnaires. Fifty-five (61%) were female, 48 (52%) were born in Africa, and 55 (63%) had health insurance. Half of African-born participants accepted HIV testing; all tested negative. The most common reasons for declining testing were lack of perceived risk for HIV and knowledge of HIV status. We identified a high prevalence of non-communicable diseases (NCDs) among health fair participants; among those tested, 77% (55/71) were overweight/obese, 39% (31/79) had blood pressure > 140/90 mmHg, and 30% (22/73) had total cholesterol > 200 mg/dL. KIIs identified community stigma and misinformation as major barriers to HIV testing among African-born individuals.

Conclusions

Residential health fairs are a feasible method to increase HIV testing among African-born individuals in Seattle. The high prevalence of NCDs highlights the importance of integrating general preventive services within HIV testing programs in this population.
